While I know there will be some people complaining that they want the single-player or even the MMO, I see this as an obvious (and pretty smart) step towards both these more complex games. Its an incredible way of supporting the studio, the IP and the future games at a (relatively) low-cost. Its not so different from what Runic is doing with Torchlight.

I wish more studios were less stubborn and considered this path of action.
